Wind break/picnic/beach items (ME15 maidstone)

Hi I am looking to take my son to the beach to celebrate his GCSE results (hopefully) I am on a budget and would like a wind break if possible if anyone has 1 or 2 (sorry to be cheeky my children are autistic so privacy is a bit better) that they are looking to rehome I would be super grateful. And anything else that could be used for picnic at the beach thankyou ever so much
